Global Standard Stratigraphic Ages main Because defining a GSSP depends on finding well-preserved geologic sections and identifying key events, this task becomes more difficult as one goes farther back in time. Source: Internet
For younger stages, a Global Boundary Stratotype Section and Point (GSSP), a physical outcrop clearly demonstrates the boundary. Source: Internet
From the 1970s, the International Commission on Stratigraphy (ICS) tried to make a single geologic time scale based on GSSP 's, which could be used internationally. Source: Internet

In fact, further eroding its value as a boundary marker, it has since been identified in strata 4m below the GSSP! citation However, no other fossil is known that would be preferable. Source: Internet
